COUNTERWEIGHT.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed December 7, 1908. Serial No. 466,346.

To all whom it may concern:

Be it known that I, MYRoN H. DETRICK, a citizen of the United States,residing at the city of Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in .Counterweights,of which the following is a specification.

My invention relates to counterweights which are attached by flexibleconnection to window sashes and the like, for the purpose of supportingthe weight thereof and holding them in balance. Such weights haveusually been made of cast metal and with the object of cheapness veryinferior metal has been used. From rough handling, to which this classof material is always subject, a considerable percentage of loss bybreakage of the eyes has usually resulted and even when the cheapestmaterials possible have been selected for the purpose of makingcastings, the expense has been considerable.

My invention provides a counterweight for such purposes, which is formedfrom a sheet metal casing adapted to hold material which will add weightthereto. The form is such that the greatest economy of space in thewindow casings and the like can be had, that weights passing each otherare guarded against binding in the window casings it they strike againsteach other therein, and the eye by which the cord or other connection isattached is so protected that it is not subject to damage in shipmentand handling. The bail which forms the eye is so shaped in connectionwith the casing that the cord is readily introduced and secured. And thecasing is easy of construction and cheap to manufacture.

The principles of my invention are illustrated in the drawings, inwhich- Figure 1 represents my improved window weight partly in section.Fig. 2 is a top view thereof, and Fig. 3 is a section on the line 33 ofFig. 1.

Further describing my invention with reference to the drawings, 1 1s ashell or caslng which is narrowed at the point 2 and given a reverseturn 3, in which is held a correspondingly reversely formed fold t ofthe top 5. The said top is provided with a depression in which is placedthe bail 6, whose ends pass through corresponding slots in the top andare formed into the hooks 7, by which it is securely fastened thereto.The eye 8 is thus formed within the top or head and the whole is socontoured that a cord introduced on one side of the bail will followinto and through the opening 8 and pass out on the other side. The bail6 should be placed far enough within the depression of the top that itis well within the protection of the edges 9. The slanted portion 10 below such edges is adapted when striking against corresponding portionson the lower ends of similar weights to cause them to pass readilywithout being stuck when moving in a window or similar casing.

in Flg. 1 the lower end of the device is shaped the same as the upperpart, a bail eye being provided therein. By this means two weights maybe connected together in alinement with each other if additional weightis desired. If this is not desired the eye and depression at the lowerpart of the weight may be omitted, but it is desirable that the lowerpart should be provided with the slanting edges, thus providing forready passage of the weights by each other. The casing 1 should befilled with suitable material for which metal drosses and slag are welladapted, and which provide a very inexpensive filling material of highspecific grgvity 1 claim:

1. In a counterweightthe combination of a casing, and an end piecesecured thereto, the said end piece being provided with a crest or rimslanted downwardly and outwardly to act as a tender and inwardly toprovide an eye seat.

2. In a counterweight, the combination of a casing and end piecessecured thereto and having a recessed portion uniformly curved inwardlyand then outwardly, and an eye secured in the recess transversely of thesaid curved portion of the recess wall.

3. In a counterweight the combination of a casing narrowed at the end,and an end piece having a slanting rim fitted over the narrowed end ofthe casing and secured thereto.

a. In a counterweight the combination of a casing, an end piece providedwith a crest secured outside the casing and provided with my hand, this8th day of F ebruary A. D. a recess inwardly and downwardly sloped 1909,in the presence of two subscribing witfrom said crest toward the center.of said nesses. I I 7 end piece, an eye seated in the recess and MYRONH. DETRI-CK. 5 protected by the rim of the end piece, and Witnesses:

weighting material inclosed in said casing. (1. K. CHAMBERLAIN,
